vb编程练习题（VB programming exercises） VB programming exercises Explanation: when doing exercises, engineering documents, standard modules, and main processes can be created by themselves, This exercise provides only one sample. First question [problem description] Please open the project file Count.vbp under the specified folder, and Module1 in the standard module In the main process, the following functions are implemented: the specified key is specified in the given data sequence The number of words that appear in the sequence, and write the result to the output file out.Txt. Explain： The 1. output statement uses Print, and if multiple expressions are output on the same line, many expressions are compact lattices Type output. 2. when you open the file, use the relative path, and do not use the absolute path, that is, you can use the file name directly. [input file] The input file in.txt has 2 rows, and the first number in the first row represents the number of numbers in the data sequence In the 1 line, second numbers represent the key to be searched, and the second line represents the given data sequence. Each number Spaces are separated from each other. [output file] The output file out.Txt is the 1 line that represents the statistical result. [input example] 555 3423551255 [output sample] Two Second questions [problem description] Please open the project file CountWord.vbp under the specified folder, and in the standard module The main process in Module1 implements the following functions: in the given word sequence, statistics are specified The number of times a keyword appears in the sequence, and writes the result to the output file out.Txt. Explain： The 1. output statement uses Print, and if multiple expressions are output on the same line, many expressions are compact lattices Type output. 2. when you open the file, use the relative path, and do not use the absolute path, that is, you can use the file name directly. [input file] The input file in.txt has 2 row
